Abstract: Studies have shown that essential oils are a natural alternative for the food industry due to their antimicrobial action. They are volatile and aromatic substances extracted from various parts of plants. They contain chemical compounds such as linalool, terpinene, cineol, among others. The objective of this study was to evaluate the antimicrobial action of tea tree, vitex fruit, manuka, myrtle and Chinese pepper oils on certain bacteria. The essential oils were used undiluted and uncombined, in their pure form, and placed on 6 mm diameter filter paper discs suitable for antibiograms, transferred to Petri dishes with the appropriate culture medium, previously seeded with the following microorganisms: Bacillus cereus, Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Salmonella Enteritidis, Salmonella Typhimurium, then incubated at 35°C for 24 and 48 hours. The analyses were carried out in duplicate and resulted in efficient action for practically all the oils on all the bacteria analyzed. All the oils showed antimicrobial action on the bacteria evaluated, with the largest inhibition halos resulting from the application of Chinese pepper essential oil (90 mm halo).
